If you like the feel of spray starch, you’ll love being able to make this quick, easy, and eco-friendly version. Here’s how to make spray starch at home!

Frankly, homemade spray starch is even better than the store-bought kind because it’s completely customizable. If you want a light starch, you can make it. If you want a heavy starch, well, you can make that, too!

Read on for how to make spray starch and options for customizing it to fit your exact needs:


Start your recipe with plain distilled water. The water where I live is hard, and so I always worry about water stains on my pristine white fabric, so I use distilled water in my iron and for laundry recipes like these.

To each cup of water, add between one teaspoon and three teaspoons of cornstarch, depending on how stiff you’d like your spray starch to be. One teaspoon will give a very light starch, suitable for a child’s dress shirt, while three teaspoons is a heavy starch, and what I use when I’m stitching jersey knit.

This is a raw recipe, so it doesn’t require cooking at all. Some spray starch recipes call for boiling the water, but all you have to do with this recipe is funnel it into a spray bottle–simple, quick, and easy to do while little kids pester you.

I believe the theory behind cooking the spray starch is to help it keep longer, so rethink this particular raw recipe if that’s a concern to you. I’ve kept this particular spray starch recipe perfectly fine in its spray bottle for several months with no spoilage.


To use this laundry starch, pour it into an upcycled spray bottle. To lightly scent it, you may add some fresh perfume to the mix–I enjoy fresh lavendar or rosemary, when I have it.

The cornstarch will always settle to the bottom of the bottle when it’s resting, so shake the bottle when you’re ready to use it, then spray your fabric damp and iron dry.

To starch large swathes of fabric, prepare a large amount of this starch solution in a bucket or sink, then dip the fabric into it, ring it out, and iron it dry.
